I have two questions I have a 2015 REV. I have a small water leak some where in the front corner of my cab. I also can't get the water pump to suck antifreeze into the system. I have been told the selector switch for water has O rings that dry and cause this problem?

Cab leak could be the AC evaporator drain hose being clogged. Ac runs in winter also to keep it lubricated and cut down on humidity for defrost.

Had the same water pump problem and ended up replacing the pump, motor worked fine just didn't move fluid.

RV roof a/c drain hose.

Thank you for the reply. The leak is in the corner up by the visor. I replaced the water pump.

I had the same water pump problem about two months ago during winterization. Initially, the pump moved about a quart of juice from the gallon container then stopped pumping. The pump was running, but not pumping. Called FR and spoke with the tech. Over the phone he told me shut the pump switch off, go to the CW connection and remove the screen, then stand off to the side and insert my finger and push the valve button. He also warned me to be ready for a gush of the juice plus residual water to shoot out and to hold my finger on the button so it didn't shoot out. It shot out in a 4 foot "jet-stream"! From what he said the system over time will develop a hydrostatic lock and the pump will go into by-pass mode and stop pumping. The pump worked fine after that.

GOOD information, you have undoubtedly saved people a good amount of money with that piece of knowledge

That is an interesting solution.
But wouldn't the pressure be released through a faucet if the pump were turned off?
